Association of serum Vitamin D level with Glycemic Status in Patients of Type 2 Diabetes Mellitus

Introduction: For development of Type 2 Diabetes mellitus, Vitamin D is thought to be a risk factor. Various studies have established the fact that Vitamin D replenishment improves glycemic status and insulin secretion in patients with Type 2 Diabetes mellitus with established hypovitaminosis D. This study was done to find out the degree of association between glycemic status and vitamin D levels in type 2 Diabetes Mellitus patients in a tertiary care center.Patient and methods: The study was done in the Department of Biochemistry, SCB Medical College, and Cuttack 48 patients of type 2 Diabetes Mellitus were taken as cases 42 healthy subjects were taken as controls. Biochemical parameters like FBS, PPBS, Urea, Creatinine, HbA1c, Lipid profile parameters were measured in both cases and controls.Results: The serum urea and creatinine levels were significantly elevated in complicated type 2 Diabetes mellitus patients as compared to healthy controls. Serum cholesterol, triglycerides, LDL Cholesterol levels also showed significant increase Vitamin D and FBS levels showed a significant negative correlation in cases and vitamin D levels were decreased in cases as compared to controls.Conclusion: As Vitamin D and FBS levels showed a significant negative correlation, and vitamin D levels were decreased in cases as compared to controls, so it can be proved that vitamin D can lead to good glycemic control and hypovitaminosis D can thereby lead to Type 2 Diabetes Mellitus.
